7th Heaven is a 1927 American silent drama movie directed by Frank Borzage. Chico has a poor life as a canal worker in Paris and dreams of a woman who loves him. One day he rescues the young prostitute Diane from her vicious sister and protects her from the police by pretending to be her husband. Both move into his attic apartment together and fall in love with each other, but their happiness seems to be short-lived.
A remake, with the number written out as a word, was released in 1937 starring Simone Simon and James Stewart. In 1995, 7th Heaven was added to the National Film Registry.
The following weapons were used in the film 7th Heaven:
The Berthier Mle 1907-15 rifle is the standard weapon for French infantrymen including Chico (Charles Farrell) and Gobin (David Butler). As the rifle's designification tells this rifle was put into French service in 1915; so a few months after the battle of the Marne took place. A more accurate choice would be the Lebel 1886 at the start of WWI.
At least, one German soldier is briefly seen with a correct Gewehr 1898.
Machine Guns
Colt Model 1895
What appears to be a Colt Model 1895, mocked up to resemble an accurate Maxim MG08, is used by German soldiers.
Maxim MG 08/15
A Maxim MG08/15 is briefly seen deployed by French soldiers during the battle of the Marne in 1914. The use of this Maxim is clearly an anachronism; like the Berthier, the MG08/15 was developed one year later.
Other
Canon de 75mm mle. 1897
Flamethrower
Near the end of the movie, Chico, Gobin, and other French soldiers can be seen using unknown flamethrowers. This model looks different from the P3, P4, and Schildt flamethrowers that were used by the French Army during WWI.
